Reliability growth modeling and planning


Reliability Growth, formerly known as RGA software, is an advanced module application available in ReliaSoft Weibull++ that allows you to apply reliability growth models to analyze data from both developmental testing and fielded repairable systems. During the development phase, it allows you to quantify and track the system’s reliability growth across multiple test phases, while also providing advanced methods for reliability growth projections, planning and management. For systems operating in the field, you can calculate optimum overhaul times and other results without the detailed data sets.

Improve reliability analysis with Reliability Growth module

Predict failures before they occur

Forecast failures with reliability growth analysis and make reliability growth projections to evaluate the reliability growth management strategy.

Monitor reliability improvements over time

Determine the feasibility of achieving a target MTBF with a given management testing strategy. Evaluate the reliability improvement from rolling out fixes for a fleet of units operating in the field.

Calculate optimum overhaul times

Easily determine the amount of testing required to demonstrate a specified MTBF, failure intensity, or reliability without the detailed data sets that would normally be required for repairable system analysis.

Quantify reliability growth across multiple test phases

Effortlessly perform reliability growth projections, reliability growth program planning and multi-phase reliability growth analysis.

Design test plans for repairable systems

Determine the test time required per system in order to demonstrate a specified reliability goal.

Experiment with sample sizes with simulation tools

Automatically analyze and plot results from a large number of data sets that have been created via simulation. Perform a wide variety of reliability tasks with integrated simulation tools.

Integrate repairable systems analysis with other processes


The Reliability Growth module facilitates the analysis of repairable systems data using the Crow (AMSAA) model. It allows you to get an overview of the system without having the large data requirements that would normally be required for system reliability analysis.

With the Reliability Growth module, you can track the progress of the system during development phase and then use ReliaSoft BlockSim in accordance with the already known results to gain more detailed information.
